This invention relates to a braking apparatus wherein the heat absorbing mass of a rotating braked element, such as a vehicle wheel, is increased by securing to, such as each wheel of the vehicle, a brake disc of such size as to constitute a heat sink capable of absorbing the heat generated by a pair of brake shoes when in braking engagement therewith, the periphery of the wheel forming a braking surface that is simultaneously engaged by a third brake shoe whereby the wheel constitutes a second heat sink capable of absorbing the heat generated by the third brake shoe.
